I've confirmed that Madden '03 stadiums work with Madden '04 so I've moved the following stadiums from Madden '03 to Madden '04:
Bears Memorial Stadium, Champaign, IL
Broncos Mile High Stadium, Denver, CO
Eagles Veterans Stadium, Philadelphia, PA
Texans Reliant Stadium (Alt), Houston, TX
College Stadium
High School Stadium
EA Sports Skydome - this one is kinda screwed up but I still left it there for information purposes.
University Stadium
Fawcett Stadium
Generic Memorial Stadium (IL) for Franklin Field, Philadelpia, PA
Generic Veterans Stadium for substituting RFK Stadium and Three Rivers Stadium.

Information Needed
The above stadiums need to be updated with their correct capacities, club seats, preview images....etc. If you would like to help just post your work but please do not post a rosters. I will instead gather everything together and post an update with credits.
Known Issues
IMPORTANT INFORMATION!
EA Skydome and Mile High stadiums have been fixed with this download. If you downloaded the stadiums prior to 10-24-2015 then you will need to download it again to get the fixed stadiums.

When selecting Mile High Stadium in exhibition mode, preview the stadium first before going into the game because then the stadium might look messed up.
